RF Diode Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm RoHS compliance status via the official Certificate of Conformance provided by Skyworks Solutions. Ensure handling procedures adhere to industry-standard electrostatic discharge precautions during storage and assembly processes.

RF Diode Selection Notes

Select this component when a single-diode configuration in an SOT-23 package is required for frequencies up to 10 GHz. Compare series resistance values against circuit drive currents to ensure adequate switching performance. Verify that the 200 V reverse voltage rating meets the peak RF voltage requirements of the specific application environment.

RF Diode Part Context

This part belongs to the SMP1352 series of large signal switching PIN diodes. Other variants in the series include the SMP1352-040LF (SOD-882) and SMP1352-079LF (SC-79). These components share similar electrical characteristics but differ in package type and parasitic inductance values.

RF Diode Replacement Considerations

Direct substitutes within the same series include SMP1352-040LF and SMP1352-079LF. Note that these alternatives utilize different packages (SOD-882 and SC-79 respectively) and possess distinct series inductance values compared to the SOT-23 SMP1352-005LF.
